ToolFS Memory

Persistent key-value storage for session data, conversation context, and agent state. Memory entries can store any JSON-serializable data with optional metadata for categorization and organization.

How It Works

1. Memory Store: Stores entries in a key-value format with optional metadata
2. Session Persistence: Entries persist across agent sessions
3. Metadata Support: Each entry can include metadata for categorization and search
4. CRUD Operations: Full create, read, update, delete operations supported

Usage

Read Memory Entry

ToolFS Path:

Copy/toolfs/memory/<entry_id>

Example:

CopyGET /toolfs/memory/user-preferences-123

// Response
{
  "id": "user-preferences-123",
  "content": "User prefers dark mode and compact layout",
  "created_at": "2024-01-15T10:30:00Z",
  "updated_at": "2024-01-15T10:30:00Z",
  "metadata": {
    "category": "preferences",
    "priority": "high"
  }
}

Write Memory Entry

ToolFS Path:

Copy/toolfs/memory/<entry_id>

Example:

CopyPUT /toolfs/memory/conversation-456
Content-Type: application/json

{
  "content": "Discussed ToolFS architecture and skill system",
  "metadata": {
    "topic": "toolfs",
    "participants": ["user", "agent"],
    "timestamp": "2024-01-15T14:20:00Z"
  }
}

// Response
{
  "success": true,
  "message": "Memory entry written"
}

List Memory Entries

ToolFS Path:

Copy/toolfs/memory

Example:

CopyLIST /toolfs/memory

// Response
[
  "user-preferences-123",
  "conversation-456",
  "session-state-789"
]

When to Use This Skill

Use Memory skill when you need to:

• Store Context: Save conversation summaries, user preferences, or agent state
• Persist Data: Keep information across sessions or conversations
• Organize Information: Use metadata to categorize and retrieve related entries
• Recall Information: Retrieve previously stored data by entry ID

Common use cases:

• "Store this conversation summary in memory"
• "Remember that the user prefers dark mode"
• "Save the current session state"
• "List all stored memories"
• "Retrieve the previous conversation context"

Entry Structure

Each memory entry contains:

• id: Unique identifier for the entry
• content: Main content of the entry (string)
• created_at: Timestamp when entry was created
• updated_at: Timestamp when entry was last updated
• metadata: Optional JSON object for additional information

Output Format

Memory operations return standardized result structures:

Copy{
  "type": "memory",
  "source": "<entry_id>",
  "content": {
    "id": "<entry_id>",
    "content": "...",
    "created_at": "...",
    "updated_at": "...",
    "metadata": {}
  },
  "success": true,
  "error": "error message if failed"
}

Present Results to User

When presenting memory results:

Copy✓ Memory entry retrieved

ID: user-preferences-123
Content: User prefers dark mode and compact layout
Category: preferences
Priority: high
Created: 2024-01-15T10:30:00Z
Updated: 2024-01-15T10:30:00Z

Copy✓ Memory entry stored

ID: conversation-456
Topic: toolfs
Stored successfully at 2024-01-15T14:20:00Z

Troubleshooting

Entry Not Found

If reading a memory entry fails:

1. Verify the entry ID is correct
2. Check if the entry exists using LIST /toolfs/memory
3. Ensure the session has access to memory operations

Write Permission Error

If writing fails:

1. Verify the session has write permissions
2. Check memory store configuration
3. Ensure entry ID is valid

Best Practices

1. Use Descriptive IDs: Choose meaningful entry IDs for easy retrieval
2. Include Metadata: Use metadata for categorization and filtering
3. Update Timestamps: The system automatically tracks created_at and updated_at
4. Organize by Category: Use metadata.category to group related entries
5. Regular Cleanup: Periodically review and clean up old entries
